摘要

Densities and viscosities of ternary liquid mixtures of aniline+acetone+(benzene or+toluene or+carbon tetrachloride or+1,4-dioxane)and their constituent binary mixtures,viz.aniline+acetone,aniline+benzene,acetone+benzene,aniline+toluene,acetone+toluene,aniline+carbon tetrachloride,acetone+carbon tetrachloride,aniline+1,4-dioxane,acetone+1,4-dioxane have been measured at 298.15 K oyer the entire composition range.The values of viscosity deviations(DELTA_(eta))and thermodynamic excess properties viz.excess molar volume(V~E)and excess Gibbs free energy of activation of viscous flow(DELTA G~(#E))have been determined for binary and ternary liquid mixtures at 298.15 K and fitted by Redlich-Kister and Cibulka equations respectively.It is concluded that experimental values of DELTA_(eta),V~E and DELTA G~(#E)compare fairly well with the corresponding theoretical values predicted by Redlich-Kister and Cibulka equations for binary and ternary liquid mixtures respectively.
